由于项目需要自学了echarts，下面将学到的东西总结如下，如果有哪里写的不好，请批评指正
一、前期准备
1、使用echarts之前先要引入echarts.js，js可以到官网下载
2、写一个div容器用来装echarts内容，这个容器必须有高度，不然看不到内容。
3、在script中获取div容器的id，根据需要写option中的参数（也许你现在还不知道option是干嘛用的，不要着急往下看），使用setoption生成图表。
（代码如下）注：后面将不再对引入js，获取id，调用option生成图表做赘述
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<!-- 为ECharts准备一个具备大小（宽高）的Dom -->
<div id="main" style="width: 600px;height:400px;"></div>
<!-- 引入echarts.js -->
<script src="js/echarts.js "></script>
<script>
获取容器的id并赋值给变量myChart
var myChart = echarts.init(document.getElementById(‘main‘));
/*用来配置参数*/
option = {
}
/*调用option生成图表*/
myChart.setOption(option)
</script>
</body>
</html>
二、各种图表使用
1、柱状图代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<!-- 为ECharts准备一个具备大小（宽高）的Dom -->
<div id="main" style="width: 600px;height:400px;"></div>
<script src="js/echarts.js "></script>
<script>
var myChart = echarts.init(document.getElementById(‘main‘));
myChart.title = ‘坐标轴刻度与标签对齐‘;
option = {
color: [‘#3398DB‘],
tooltip : {
trigger: ‘axis‘,
axisPointer : { // 坐标轴指示器，坐标轴触发有效
type : ‘shadow‘ // 默认为直线，可选为：‘line‘ | ‘shadow‘
}
},
grid: {
left: ‘3%‘,
right: ‘4%‘,
bottom: ‘3%‘,
containLabel: true
},
xAxis : [
{
type : ‘category‘,
data : [‘Mon‘, ‘Tue‘, ‘Wed‘, ‘Thu‘, ‘Fri‘, ‘Sat‘, ‘Sun‘],
axisTick: {
alignWithLabel: true
}
}
],
yAxis : [
{
type : ‘value‘
}
],
series : [
{
name:‘直接访问‘,
type:‘bar‘,
barWidth: ‘60%‘,
data:[10, 52, 200, 334, 390, 330, 220]
}
]
};
myChart.setOption(option)
</script>
</body>
</html>
运行结果
2、折线图
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id="pic4" style="width: 600px;height:400px;"></div>
<script src="js/echarts.js"></script>
<script>
var myChart13 = echarts.init(document.getElementById(‘pic4‘));
var data = [];
option15 = {
title: {
text: ‘曲线‘,
},
tooltip: {
trigger: ‘axis‘,
},
legend: {
data:[‘昨日(11月8日)‘,‘今日(11月9日)‘]
},
grid: {
left: ‘1%‘,
right: ‘1%‘,
bottom: ‘3%‘,
containLabel: true
},
toolbox: {
show: false,
feature: {
dataZoom: {
yAxisIndex: ‘none‘
},
dataView: {readOnly: false},
magicType: {type: [‘line‘, ‘bar‘]},
restore: {},
saveAsImage: {}
}
},
color:["red","#CD3333"],
xAxis: {
type: ‘category‘,
boundaryGap: false,
data : [‘1‘,‘2‘,‘3‘,‘4‘,‘5‘,‘6‘,‘7‘,‘8‘,‘9‘,‘10‘,‘11‘,‘12‘,‘13‘,‘14‘,‘15‘,‘16‘,‘17‘,‘18‘,‘19‘,‘20‘,‘21‘,‘22‘,‘23‘,‘24‘]
},
yAxis: {
type: ‘value‘,
name: ‘单位（kW）‘,
axisLabel: {
formatter: ‘{value}‘
}
},
series: [
{
name:‘昨日(11月8日)‘,
type:‘line‘,
data:[110,106,110,110,318,119,205,256,156,309,256,306,206,356,456,486,565.45,234,156,206,126,256,150,276],
},
{
type:‘line‘,
name : ‘今日(11月9日)‘,
data:[210,136,120,120,118,219,195,176,156,329,356,346,406.54,256,156],
}
]
};
myChart13.setOption(option15);
</script>
</body>
</html>
运行结果
3、饼图
由于代码重复就不浪费地方写所有代码，直接替换（一）中的option{}就可以
option = { title : { text: ‘某站点用户访问来源‘, subtext: ‘纯属虚构‘, x:‘center‘ }, tooltip : { trigger: ‘item‘, formatter: "{a} <br/>{b} : {c} ({d}%)" }, legend: { orient: ‘vertical‘, left: ‘left‘, data: [‘直接访问‘,‘邮件营销‘,‘联盟广告‘,‘视频广告‘,‘搜索引擎‘] }, series : [ { name: ‘访问来源‘, type: ‘pie‘, radius : ‘55%‘, center: [‘50%‘, ‘60%‘], data:[ {value:335, name:‘直接访问‘}, {value:310, name:‘邮件营销‘}, {value:234, name:‘联盟广告‘}, {value:135, name:‘视频广告‘}, {value:1548, name:‘搜索引擎‘} ], itemStyle: { emphasis: { shadowBlur: 10, shadowOffsetX: 0, shadowColor: ‘rgba(0, 0, 0, 0.5)‘ } } } ] };
运行结果
4、全国地图
由于地图比较复杂，所以把全部代码展示出来
china.js可以到官网下载所有代码，在echarts/map文件夹中可以找到china.js,

5、城市地图（以北京为例）
beijing.js可以到官网下载所有代码，在echarts/map/province文件夹中可以找到beijing.js,其他城市的使用同样方法直接引入对应的js即可
